Not a bug, but no right category for it.
I think dissapearance of player bodies after death is too quick.
Right now its about 5-10 minutes.
Why I think is too short.
First you can wander around and unexcpectedly find somebody's corpse and loot it for your suprise.
In longtimed firefight sometimes even 15 minutes not enough and all you can loot after is nothing.
Maybe it should stay at least for 1 hour?
I know its performance wise but still.
I had once idea on some forums where dead player dissapear on second restart only and only first one they become zombies with gear.
